Quadruped Military Vehicles From Back In The Day


While Boston Dynamics’ Big Dog is pretty impressive, check out this video of the US Army’s first attempt at a quadruped vehicle. Created in the early 1960s with the help of GE, this Army experiment was the first successful attempt of replicating a four-legged animal with a mechanical machine.

This “Walking Truck” was driven by a single operator who moved each of the vehicle’s legs using force-feedback hydraulic levers. Choreographing the machine’s movement was quite complicated, and during testing the Army found that the operator needed a mental break after only 15 minutes of use. As you can see in the video, the vehicle flexes some serious muscle. It kicks a Jeep out of its way with little effort, but it is still able to gently step on a light bulb without breaking it, due to the level of tactile feedback received by the operator.

If it weren’t for government budget cuts, we could be living out [George Lucas’] dream of AT-AT based combat right this minute!

  1. The light bulb demo is awesome. It looks cool, and proves nothing. Since the light bulb is on a pillow, you don’t need any tactile feedback — the operator just needs to visually check that the light bulb isn’t pushed too far into the pillow. The quad would be cool today let alone 1960, but that particular ‘demo’ is a bit disingenuous.

  2. This shows that the mechanical parts and functionality were there all the way back in the 1960’s but the microcontroller controls needed another 50 years (!) to catch up.

  3. The first makes me think about the possibility of taking a small animal or insect and using it’s brain to operate the thing most of the time and allowing a human to override for specific tasks. And of course that would have to bring up ethical considerations. A cockroach brain should certainly be able to operate such simple lets with feedback.

    The second video is eerie, the legs look like they are moving so naturally.
